Public transportation in many states are using these wands I have seen them on TV. Not sure who they se there are several I am sure. However it looks like our 2 billion dollar contract was in CA. So this does make sense for the OPTI products.
Is this a coincidence "The governor’s $2 billion budget proposal would channel money into Personal Protection Equipment (PPE), testing and other safety measures, with a focus on kindergarten through second grade"
